We’re solving every piece of the battery puzzle

Seeo’s safe and energy-dense solid-state cell can power everything from cars to homes to aircraft.

Key Milestones

  1. 2007

    Seeo is founded with the goal of creating a new class of high-energy rechargeable lithium-ion batteries based on a nanostructured polymer electrolyte initially developed at Lawrence Berkeley National Laboratory.

    SEEO deep battery cell development experience

  2. 2008

    Seeo develops DryLyte, a lithium-stable solid-state electrolyte/separator.

    Seeo - safety of solid-state battery cells

  3. 2011

    Seeo moves to Hayward and establishes a pilot line to develop large-format cells and processes.

  8. 2017

    Seeo takes a leap forward with its next-generation polymer electrolyte, which enables cells with NCM cathodes.

  9. 2018

    Seeo builds 250Wh/kg (15 Ah) cells.

    Seeo develops a next-generation solid-state electrolyte/separator that can be operated with NCM cathode active material.

  10. 2019

    Target: Development of a solid-state, high-energy (>20 Ah) battery cell with 350Wh/kg energy density.

  11. 2020

    Target: Development of a solid-state, high-energy (>30 Ah) battery cell with 450Wh/kg energy density.
